How these offers were matched

Exact manufacturer part number, same manufacturer and 405.0W bin, and identical source technical title after removing only terminal package/clearance sale labels. No fuzzy-title merge. Matching known electrical/design specs were checked; source collision flags and conflicting wattages/specs are excluded. Purchase units and minimum orders remain separate on each offer.

WHAT WE ACTUALLY OBSERVED

Prices have a history.

Observations keep their original source dates and purchase scopes. Historical lows are separate from current availability. Unpriced and configuration-dependent offers are never treated as exact-price lows.

No exact-model certification record has been reviewed for this listing in our evidence collection. This does not establish whether the product is certified.

How to verify the model and scope

Rated power is a starting point.

Conceptual panel-energy map, not a prediction for this product. A watt rating does not establish daily watt-hours; location, season, shade, orientation, temperature and system losses still matter. Explore seasonal solar assumptions
